Laparoscopy-guided biopsy in diagnosis of liver disorders in children.
To determine the safety and advantages of laparoscopic liver biopsy in pediatric liver disorders, we reviewed the medical records of 80 children affected by liver disease of various etiologies who underwent this procedure from 1986 to 1996. The main indicators for laparoscopic biopsy were increased risk of bleeding (i.e., mild to moderate coagulation abnormalities in patients probably affected by cirrhosis) and/or previous poorly informative blind needle liver biopsy (65 cases), and the need for a large amount of liver tissue for biochemical assays (10 cases). After inspection of the liver surface, at least two core biopsies were performed using a Tru-cut needle. We encountered difficulties with the biopsy in only four cases, due to a hard consistency of the liver. Bleeding time from the liver orifice was greatly reduced by positioning a fibrin plug (50-120 s vs 5-10 s, on average). In 15 patients, a large excisional biopsy was also successfully performed. Our results confirm an important role for laparoscopy in the diagnosis of cirrhosis (30% of bioptic false negative diagnoses in this series) and show that in selected cases laparoscopy-guided needle or excisional biopsy is an easy, useful and safe alternative to percutaneous blind liver biopsy.
